Sheet-fed offset: inking rollers

In the modern offset and web-offset systems the rollers covering plays an important role in the qualitative output and makes the system more economical to run. TecnoRulli® has prepared and tested ideal coverings for the most demanding printers according to the most severe conditions. The formulation of the compounds has allowed us to obtain a product which has a high resistance to heat, to solvents and to abrasion. The product has a dimensional stability, a superficial elasticity and softness together with a guarantee of optimal qualitative and long lasting performance.

Flexo, Converting and Industrial Coverings

Over the years, the printing on flexo has been the field that has the greatest technological propulsion and a certain qualitative increase.The major machines producers and the raw materials suppliers have been united by a common effort to give to the printer a finished high quality product and ecologically appropriate, in order to anticipate the market requirement.The elastomeric for inking roller has had a significant evolution to meet the chemical characteristic changings of new inks and the increasing pressing needs of uniformity and quality of print.To cover all needs, from solid area with high quantity of ink, to the halftone printing with controlled metering, Tecnorulli has production in new series of compounds available in hardnesses from 45 to 80 Shore A.The grinding and finishing process is made on new high-tech machines that guarantee high levels of precision in dimensional measures and surface.Tecnorulli s compounds have been studied for ensure to printers a long lifetime and good efficiency in order to reduce costs resulting from stops and the remaking of the coating itself.Each phase of the working is done inside the Company for being able to guarantee high qualitative standards, flexibility and an elevated service to the Customers.The corrugated boards printing is a very important field of the flexo section. The used inks are with water (exceptionally solvent).Tecnorulli s coverings for the ink vibrating rollers guarantee an optimal resistance to the inks also with the presence of antifoaming additive.The range of compounds available includes coatings for rollers with high abrasion resistance available in different hardnesses.For this type of rollers Tecnorulli s laboratories have been developed special double coatings too; the lower coating with a soft compound with a great elasticity and compressibility, and the top coating with a harder compound very resistant to wear.On these rollers all kind of surface grooves are performed by CNC machines.

Tecnorulli has prepared a new series of coverings ideal for high and very high speed usage, tested in the strictest operating conditions. The new coverings offer excellent performance in machines with very high rotation, with the aid of carefully studied characteristics of hardness and mechanical resistance, offering a valid contribution to the quality yield and operating economy of today's web-offset machines. The minimum heat production during rotation and its homogenous and complete dissipation also through the covering stabilise these new compounds in operation at lower temperatures, thus guaranteeing better printing conditions, perfect dimensional stability and longer lifetime.

HISTORY

In 1948 the Samoggia Brothers, having completed their studies at the famous College Aldini Valeriani of Bologna, started to experiment with the covering of printing rollers with special compounds.They started their activity in a small basement in the old town centre of Bologna, and after a few years the firm improved its production capacity thanks to favourable market conditions.With a constant increase and a progressive specialisation which led to the establishment of Tecnorulli in the early 70s, our company is now recognised as a leader in covering printing and industrial rollers.

MISSION

Products reliability, Innovation in research, flexible service, are the lead values that Tecnorulli follows all the time.
